Altough, the reddit redesign sucks on mobile too.
The problem here is the hostile relationship from the companies to their customers.
And even if they say security they usually bundle it with other changes, along with not even saying what kind of security change.
Give me a vulnerability tracker and what has been fixed, and I'll actually update your app.
For me, the "added security" is just not worth it MOST of the time. Partially due to actually only installing apps that don't even have the capability to do much/any damage, due to it only having permission to access parts I don't deem dangerous.
We're talking about phone apps. 99% of the time this just isn't the case and the remaining 1% is for issues so widely broadcast you would absolutely know.
For desktop software, most seem to, sadly, be self updating or a website.
For example, youtube now has a miniplayer when playing a playlist on desktop. I find that "feature" to be absolutely atrocious and would rather do without it. But due to it being a website they changed it to make it impossible to turn it off.
